3. What Is Wasm? The boring answer: It’s just another bytecode format
4. WebAssembly’s Strengths • Security sandbox • Cross-platform, cross architecture • Fast startup and execution • Ideally, can support any language Good for the browser, great for the server
11. Orchestrating Wasm Nomad, Kubernetes, etc.
12. Fermyon Cloud and Nomad •Easier to write a driver •More efficient for scheduling non-containers •We built a custom massively scaling runtime •But... Kubernetes is everywhere
13. Kubernetes and Spin • Step 1: Virtual Kubelet • This was Krustlet • We view it as an objective failure • Step 2: Containerd • Microsoft wrote it for AKS • It was committed to containerd as a shim • Extended to run in any Kubernetes cluster • Coming to EKS as official add-on soon • Step 3: Spin Kuberntes Plugin • Make it easier to package spin apps as containers • Requires a "wrapping container" • Step 4: Native Support for OCI Artifacts • Liquid Reply working with Fermyon on support • Greatly simplify user experience
14. More Kubernetes Stuff •Support additional triggers in Kubernetes • Redis • SQS •More Examples in Spin Up Hub and improved Documentation •And finally....
15. Spin on Openshift! •Working in collaboration with Red Hat and Liquid Reply •Extended crun to support call Spin binary •Let's see a demo!
